Marion Jones made a winning return to action in Europe by taking the 100m at the FBK Games in the Netherlands.
Jones is keen to get back to top form this season
The 30-year-old American made a slow start but recovered to win in 11.16 seconds with Briton Emma Ania second.
Britain's former European Under-23 champion Rebecca Lyne won the 800m in a personal best of two minutes 0.04secs.
Christian Malcolm and Darren Campbell were third and fifth respectively in the men's 100m, which was won by Nigeria's Olusoji Fasuba in 10.33secs.
Jones returned to action earlier this month in Mexico after an 11-month absence during which she battled injuries and unsubstantiated doping allegations raised by the Balco steroid scandal.
It feels good. The weather didn't look good but I felt like I was ready to go
The former world and Olympic champion, who has never tested positive and has consistently denied using performance-enhancing drugs, came back to Europe having finally cleared her name.
She hit her stride in the middle of the race and pulled away from the rest of the field to triumph.
"A win is a win," she said. "I am extremely delighted. I want to go back home and train for the nationals. I hope I can keep this form.
"It feels good. The weather didn't look good but I felt like I was ready to go."
